Further, by the action of this enzyme there is a better redistribution of the water phase to the phase of pentosans (gluten becomes more extensible), resulting in improved bread volume (KATINA, 2003).
It can perform Solvent Retention Capacity tests to determine water absorption in a flour sample, breaking it down to the degree of absorption contributed by its glutenin, pentosans and damaged starch portions.
Chemically, bagasse contains about 50% a-cellulose, 30% pentosans, and 2.
The major factors contributing to the farinograph absorption include protein content, starch, damaged starch, pentosans and gluten strength (Vizitiuand Danciu, 2011).
For the WSB, it was observed that the longer storage time led to decreases of the pH, the pentosans, and holocellulose contents and increases of the klason lignin, alkali solubility, and solvent extractives, which plays a large part in the reduction of the fiber's quality.

The carbon compounds found in fibrous bulk ingredients include cellulose, lignin, hemicelluloses and pentosans.
